Area2D

A region of 2D space that detects other CollisionObject2Ds entering or exiting it.

FNV24: [8R9X5]

Area2D is a region of 2D space defined by one or multiple CollisionShape2D or CollisionPolygon2D child nodes. It detects when other CollisionObject2Ds enter or exit it, and it also keeps track of which collision objects haven’t exited it yet (i.e. which one are overlapping it).

This node can also locally alter or override physics parameters (gravity, damping) and route audio to custom audio buses.

This object emits the following signals:

Superclasses

class CollisionObject2D
Abstract base class for 2D physics objects.

Conformances

protocol CustomStringConvertible
A type with a customized textual representation.
protocol Equatable
A type that can be compared for value equality.
protocol Hashable
A type that can be hashed into a Hasher to produce an integer hash value.
protocol Identifiable<ID>
A class of types whose instances hold the value of an entity with stable identity.
protocol VariantRepresentable
Types that conform to VariantRepresentable can be stored directly in Variant with no conversion. These include all of the Variant types from Godot (for example GString, Rect, Plane), Godot objects (those that subclass SwiftGodot.Object) as well as the built-in Swift types UInt8, Int64 and Double.
protocol VariantStorable
Types that conform to VariantStorable can be stored in a Variant and can be extracted back out of a Variant.

enum SpaceOverride

Type members

class var godotClassName: StringName

Instance members

var angularDamp: Double
The rate at which objects stop spinning in this area. Represents the angular velocity lost per second.
var angularDampSpaceOverride: Area2D.SpaceOverride
Override mode for angular damping calculations within this area. See SpaceOverride for possible values.
var areaEntered: Signal7
Emitted when the received area enters this area. Requires monitoring to be set to true.
var areaExited: Signal8
Emitted when the received area exits this area. Requires monitoring to be set to true.
var areaShapeEntered: Signal5
Emitted when a Shape2D of the received area enters a shape of this area. Requires monitoring to be set to true.
var areaShapeExited: Signal6
Emitted when a Shape2D of the received area exits a shape of this area. Requires monitoring to be set to true.
var audioBusName: StringName
The name of the area’s audio bus.
var audioBusOverride: Bool
If true, the area’s audio bus overrides the default audio bus.
var bodyEntered: Signal3
Emitted when the received body enters this area. body can be a PhysicsBody2D or a TileMap. TileMaps are detected if their TileSet has collision shapes configured. Requires monitoring to be set to true.
var bodyExited: Signal4
Emitted when the received body exits this area. body can be a PhysicsBody2D or a TileMap. TileMaps are detected if their TileSet has collision shapes configured. Requires monitoring to be set to true.
var bodyShapeEntered: Signal1
Emitted when a Shape2D of the received body enters a shape of this area. body can be a PhysicsBody2D or a TileMap. TileMaps are detected if their TileSet has collision shapes configured. Requires monitoring to be set to true.
var bodyShapeExited: Signal2
Emitted when a Shape2D of the received body exits a shape of this area. body can be a PhysicsBody2D or a TileMap. TileMaps are detected if their TileSet has collision shapes configured. Requires monitoring to be set to true.
var gravity: Double
The area’s gravity intensity (in pixels per second squared). This value multiplies the gravity direction. This is useful to alter the force of gravity without altering its direction.
var gravityDirection: Vector2
The area’s gravity vector (not normalized).
var gravityPoint: Bool
If true, gravity is calculated from a point (set via gravityPointCenter). See also gravitySpaceOverride.
var gravityPointCenter: Vector2
If gravity is a point (see gravityPoint), this will be the point of attraction.
var gravityPointUnitDistance: Double
The distance at which the gravity strength is equal to gravity. For example, on a planet 100 pixels in radius with a surface gravity of 4.0 px/s², set the gravity to 4.0 and the unit distance to 100.0. The gravity will have falloff according to the inverse square law, so in the example, at 200 pixels from the center the gravity will be 1.0 px/s² (twice the distance, 1/4th the gravity), at 50 pixels it will be 16.0 px/s² (half the distance, 4x the gravity), and so on.
var gravitySpaceOverride: Area2D.SpaceOverride
Override mode for gravity calculations within this area. See SpaceOverride for possible values.
var linearDamp: Double
The rate at which objects stop moving in this area. Represents the linear velocity lost per second.
var linearDampSpaceOverride: Area2D.SpaceOverride
Override mode for linear damping calculations within this area. See SpaceOverride for possible values.
var monitorable: Bool
If true, other monitoring areas can detect this area.
var monitoring: Bool
If true, the area detects bodies or areas entering and exiting it.
var priority: Int32
The area’s priority. Higher priority areas are processed first. The World2D’s physics is always processed last, after all areas.
func getOverlappingAreas() -> ObjectCollection<Area2D>
Returns a list of intersecting Area2Ds. The overlapping area’s collisionLayer must be part of this area’s collisionMask in order to be detected.
func getOverlappingBodies() -> ObjectCollection<Node2D>
Returns a list of intersecting PhysicsBody2Ds and TileMaps. The overlapping body’s collisionLayer must be part of this area’s collisionMask in order to be detected.
func hasOverlappingAreas() -> Bool
Returns true if intersecting any Area2Ds, otherwise returns false. The overlapping area’s collisionLayer must be part of this area’s collisionMask in order to be detected.
func hasOverlappingBodies() -> Bool
Returns true if intersecting any PhysicsBody2Ds or TileMaps, otherwise returns false. The overlapping body’s collisionLayer must be part of this area’s collisionMask in order to be detected.
func overlapsArea(Node?) -> Bool
Returns true if the given Area2D intersects or overlaps this Area2D, false otherwise.
func overlapsBody(Node?) -> Bool
Returns true if the given physics body intersects or overlaps this Area2D, false otherwise.
